sTUFFlNG-Box PACKING.

To all whom it may con/cern:

Be it known that ISAMUEL M.h Guss, a citizen of the United States, and a resident of the city of. Reading, county of Berks, and State of Pennsylvania, have invented certain new vand, useful Improvements in Stuffing-Boxl Packing, of which the following is a y specification.

My invention relates to stuffing-box packing adaptedparticularly for use in connection with hydraulic machines; and it `'consists in the improved form and arrangementv of conical metallic packing-rings in connection with an inclosing correspondingly bored clamping-ring therefor and means for setting up the same to maintain a uniformly tight packing without undue friction, as fully described in connection withthe accompanying drawing, the novel features being specificallyv pointed out in thev claims.

The drawing is a longitudinal sectionall view of a stufIing-box provided with my improved packing applied theretoin preferred ZOIHI. j i i i Fitted to the stuffing-box 2 is a clampingring 3, the bore of which, as shown, is oppositely tapered from a point midway of its length, rso as to form an opening iiared at each end. This ring incloses a pair of longitudinally-split packing-rings '4, of Babbitt metal or the like, bored to fit the rod 5 and of conical form, exteriorly corresponding with the oppositely-flared opening of thefinclosing ring 3.' These conical packing-rings are arranged withftheir smallery diameter ends adjacent and with theirlarger diameter outer ends ,projecting oppositely through the inclosing ring 3, so that an endwise closing-together ressure exerted upon said projecting ends will cause the packing-rings to be correspondingly closed upon the rod 5. In order t at this wedging action of the conicallybored clamping-ring 3 upon the packingrings 4 may be vmodified, so as to secure a proper packing ,pressure upon the rod under varying conditions without liability of excessive friction and binding ofthe parts, and at the same timeprovide for continuous and automatic lubrication by lmeans of the operating medium, I preferably make this inclosing ring, 3 of pine-wood or similar porous fibrous material, adapted to provide a properly-yielding and elastic wedging action upon the metal packing-ring and to permit the passage therethrough of the operating medium Specification of Letters Patent Application filed April 9, 1906.

the packing-rings, said chamber thus serving as a lubricating-chamber by retaining therein the supply of operating medium finding its way thereto through the said porous matevrial or around the reciprocating rod. 1

The conical packing-rings 4 are divided `into approximately hemispherical parts, as

usual, adapted to be progressively closed upon the rod 5 as wearoccurs -by endwise movement thereof in the inclosing ring 3, and the latter may also be similarly divided into hemispherical parts, as indicated, though this is not required and is merely preferable because it enables them' to be more readily placed or withdrawn fromv position in the stuffing-box. conical packing-rings as required and for completing the packing of the rod 5, I employ/as indicated, a thin sheet-metal washer 10, preferably of copper, interposed between the projecting end of the packing-ring 4 and any suitable compressible packing l l through which latter said washer l() is pressed against the projecting packing-ring 4 and the clamping-ring 3 by means of an adjustable gland 12, thus providing a metallic covering against the ends of the parted rings as-a support for the packing material 11 in closing'together the packing-rings 4 by end movement thereof. 1

, T he preferred construction of the clamping-ring 3 from pine-wood or like non-metallic material is of decided advantage, because .the swelling of such material in hydraulic service insures suflicient tightening of the Ipacking-rings upon the rod, while at the same time allowing such yielding as will prevent any binding or excessive wearing action of the parts and providing for utilizing the operatingmedium itself as an effective lubricant in the intermediate annular chamber 6.

What I claim isj l. In a stuffing-box packing, a clampingring having an oppositely flared opening,

and a pair of split packing-rings of conical form arranged with their smaller ends contiguous and their larger ends projecting oppositely through said clamping-ring substantially as set forth. n

2. A stuffing-box packing comprising a clamping-ring having an oppositely-flared opening, a pair of splitpacking-rings `of -conical form arrangedwith their smaller ends contiguous and their larger ends projecting op-y positely through said clamping-ring, a comformedbetween the adjacent inner ends of To provide for setting up the IOO IIO

said clamping-ring, and means for pressing together said packing-rings, the porous material of said clamping-ring enabling the oporating medium under pressure to occupy said annular lubricating-chainber.

In testimony whereof I aiiix my signature in the presence of two Witnesses.

and an adjustable gland, substantially as set forth.

3. A hydraulic stuing-box packing comprising a clamping-ring of porous material having an oppositely-iiared opening, a pair of split conical packing-rings Within said clamping-ring arranged with their smaller ends adjacent and forming between them an annular lubricating-chamber and With their larger ends projecting oppositely through pressible end packing and interposed Washer, I
